Application filed August 25, 1924. Serial No. 734,125.

position of the lever after a tongue has been struck out from the-uppermost flange;

Figure 3 is a view similar to Figure 2 but showing the position of the lever after the struck-out tongue has been bent against the lower-most flange to provide a finished joint; I a

Figure 4 is a detail elevation of the lever; Figure 5 is a detail elevation of the lower handle Figure 6 1s a top plan view of the lower handle;

Figure handle;

. Figure 8 is a top plan view of the upper 7 is a detail elevation of the upper handle.

Referring now to the drawings in which like characters of reference designate corresponding parts throughout the several views, the numerals 1 and 2 respectively designate sheet metal panels that are preferably secured to a suitable frame (not shown) of a vehicle body. For efl'ecting a joint between the panels at the adjacent edges thereof, the lower panel 2 is preferably formed with an outwardlyembossed portion 3 that connects into aninwardly extending flange 4, while the upper panel 1 is preferably embossed outwardly to provide a strip of molding 5 for overlapping the embossed portion 3 of the lower panel and is provided at the free edge of the molding with a close return-bent portion 6 that engages the curved inner face of the molding and connects into an inwardly extending flange 7. This flange preferably projects slightly beyondthe inner edges of the flange 4 and is adapted to be cut at spaced pointsby means of a pair of pliers 8 to provide a lurality of tongues 9. ,These tongues are su sequently bent by the pliers over and against the flange 4 for holding the embossed portion 3 in firm engagement with the return-bent portion 6 to secure the panels together. The pliers 8 preferably comprise a pair of handles 10 and 11 respectivelyhaving bifurcated end portions 12 and 13, pivoted upon a suitable bolt 14. The furcations of the handle 11 preferably terminate in spaced jaws'15 having serrated faces 16 while the furcations of the handle 10 are preferablyconnected. at their ends by a jaw 17 that is also provided with a serrated face 18 and is adapted to cooperate with the jaws 15 to clamp the flanges 4 and 7 together.

In ordenthat the tongues 9 may be struck out from the flange 7 and subsequently bent over and against the flange 4 by means of the same tool, I preferably provide a lever 19 that is pivoted upon the bolt 14 between thefurcations of the handle 11 and that is provided beyond the pivot bolt 14 with the spaced projections 20 and 21 respectively. The projection 20. is preferably provided with shearing edges 22 which are adapted to cut 'out'the tongues 9 when the lever 19 is moved upwardly in the direction of the arrow shown in Figure 2 of the drawing and is provided with a forwardly inclined end portion 23 for pressing these tongues downwardly to the position shown in Figure 2 of the drawing after they are cut. The projection 21 is preferably longer than the projection 20 and is provided with a flat face 24 that is adapted to move upwardly between the spaced jaws 15 when the lever is moved downwardly, as shown by the arrow in Figure 3 of-the drawing, for pressing the tonguesupwardly against the lower face of the flange 4 to provide a finished joint.

For normally holdingthe lever 19 in spaced relation to the handles 10 and 11 so that it will not interfere with the use of the handles, I preferably provide a coil spring 25 that is terminally connected to a screw 26 threadedly engaging the lever 19 and to a clip 27 mounted on the bolt 14.

From the foregoing description, it will be readily apparent that I have provided a very practical pair of pliers that is equipped with means for moving the flanges of the panels in opposite directions so that the adjacent edges of the panels will be drawn together to form a tight joint and for subsequently holding these flanges together. while the tongues are cut from one flange and subsequently bent over and against the other flange. Thus, I have provided a very simple tool that may be readily used by any unskilled person for properly uniting adjacent panels of a vehicle body. I

While it is believed that from the fore going description, the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to when desired as fall within the sco e of what is claimed.
